Sorry, can't help then... I'm on Vista and it runs fine, it was just the 3d window problem.

Stupid question - drivers up to date? 

i believe my drivers for my ATI video card are up to date, evne tho the card itself isnt the greatest but yeah. i even tried using hammer , and dragging the hammer 3.5 exe into the folder and running that. even it had the same issue.. :( 

I tried lots of editors and the easyest for me was Quark :\ but few people like this editor in here... 

Microsoft took it out of Vista and Windows7. I know because I had the same problem. I found a copy of this file somewhere and put it in the Worldcraft folder and the problem went away. It might work for you. The version of the .dll I have is dated ‎Monday, ‎July ‎14, ‎1997, ‏‎11:00:00 AM.

That said, I recommend trying gtkRadiant. It only took me a day of fooling around to get used to it.

Would go away with an open source version of WC.

Once I've got modelling tasks out of the way I'll probably give BSP editor a proper try. 

Gets my vote and having used it for so long, I find it difficult to understand what it is about it that stops more people using it (Quake1SP)? 

No Undo function brakes it for me. Otherwise I found it very good. 

No Undo function O_O

for me, it's not so much that anything stops me from using bsp editor, but that i have sikkpin's qe3 which i already like.

but yeah, if i was changing now, the lack of an undo would probably make me not consider it too. :P 

Can you use the mouse or is it arrow keys only?

Ahem.

No undo isn't that bad, but its such a basic feature that if it's not there then there's most likely a load of other stuff that I'd want and isn't there either. 

not even dropping that d3d DLL file fixed the problem :( quake hates me right now 

Not sure if you are looking for multiple levels of undo but it certainly has CTRL+Z, and it has Save For Undo.

Without wishing to sound pompous (but it will do so never mind) I have never really found a need for undo except where I have moved several hundred brushes and then changed my mind (this is typicaly when handling large areas of terrain). If I think I am going into dodgy territory with something, I generally save a new version.

Have a look at http://www.bspquakeeditor.com/doc/ 

Yes, mouse driven. It is also very configurable all round e.g. for keyboard shortcuts.

For example: with mouse in right hand - select a brush's face in the 3D window with a left-click, select a texture in the texture window with a left-click, then with the left hand ALT + F to apply that texture to the face.

Then: left-click and hold + LSHIFT to stretch the texture or maybe CTRL+SHIFT and left mouse-click to rotate the texture. Perfect for aligning textures to angled trims. 

I'm not that good at making architecture so I often end up going back with what I have just changed. One level undo isn't enough then. I have learned how to use bspeditor some time ago and made few rooms with it. At the moment I'm using qe3 and hammer.
The point is people have made beautiful maps with all kinds of editors.

@Iluvquake - did you try to enable/disable the "Filter Textures" option in 3D View configuration tab in WC/Hammer? 

took a quick look at the link... the face extruding looks interesting. i've never seen that in a quake editor before.

also, Save For Undo sounds like 3ds max's hold/fetch command where you can save the file in the ram and then 'fetch'/load it later. 

That sounds ok. Face extruding sounds like an odd feature to have in a brush based editor since it would seemingly promote convex (illegal) brushes.

Something to look at since I doubt that's the case. 

Basically adds (extrudes) a new brush to the selected face, so nothing illegal. If you check out the link above, it explains it in pictures far better than I could in words. It works, so building fancy shapes is a doddle. 

Finally got to skim it - seems good, there's a lot of useful features in there after all. 

Mdls in the 3d window - nice. 

Having a look. Not used to this amount of automated stuff - when it was introduced to 3D packages I avoided using it.

Not that its bad, most shapes in Quake are simple enough, until you get to the detailing - rooms, stairs etc. 

It even allows you to configure the font.

Not going to, but that's one step beyond in terms of genuine user-friendliness and not windows user-friendliness. 

Nowadays, I hardly ever use it. In fact the only time I can remember is when I want to do a quick check on something I am building and quickly drop a large 'room' around the map: create room, compile (I have created a large number of differing batch files to call from the editor), review in Quake, and then back to the map with a CTRL+Z to remove the 'room' I created earlier.

I doubt that I use more than 75% of the editor's capability and regularly discover new things, especially shortcuts. 

just installed radiant on win7 and got 2d and 3d windows showing nothing like this:

any idea if it's fixable? (got it ok on other machine with win7) 

Disable the desktop theme (Aero) in the compatibility settings for gtkradiant.exe. 

:) 

but please... there is no i.
